the buds are very small, i had the same problem on the motherplant that i grew in hydro, its just a very bad phenotype, i had 2 of these in the package of 10 seeds, 8/10 was very good plants with very big yields of 125 grams/plant wich took very less space in the growroom. i yielded 170grams of this pheno in the rdwc system but the plant was very big ( took almost the whole tent in) so i reccomend not groIng this in hydro, it also finishes faster in soil with autumn colors at the end.
i have a feeling the buds will get more weight in the coming week this is also only a 104watt LED.
